Re: Air crew exposures, regulatory issues
Please look at
Implementation of Article 42 of Council Directive 96/29/Euratom (also known
as the 'Basic Safety Standards Directive')
specifically relevant to the protection of air crew from the effects of
cosmic radiation.

The Radioactive Substances Act 1993:
Implementing The Revised Basic Safety Standards Directive Euratom 96/29 of
13 May 1996
...................................................
Article 42
Protection of air crew
Each Member State shall make arrangements for undertakings operating
aircraft to take account of exposure to cosmic radiation of air crew who are
liable to be subject to exposure to more than 1 mSv per year. The
undertakings shall take appropriate measures, in particular:
-to assess the exposure of the crew concerned,
-to take into account the assessed exposure when organizing working
schedules with a view to reducing the doses of highly exposed aircrew,
-to inform the workers concerned of the health risks their work involves,
-to apply Article 10 to female air crew.
------------------
Article 10
Special protection during pregnancy and breastfeeding
1. As soon as a pregnant woman informs the undertaking, in accordance with
national legislation and/or national practice, of her condition, the
protection of the child to be born shall be comparable with that provided
for members of the public. The conditions for the pregnant woman in the
context of her employment shall therefore be such that the equivalent dose
to the child to be born will be as low as reasonably achievable and that it
will be unlikely that this dose will exceed 1 mSv during at least the
remainder of the pregnancy.
2. As soon as a nursing woman informs the undertaking of her condition she
shall not be employed in work involving a significant risk of bodily
radioactive contamination.

Subject: Air crew exposures, regulatory issues
The issue of air crew exposure is highlighted in Europe by their regulatory
scheme. They are adopting the ICRP 2 rem (.02 Sv) annual limit (really 0.1
Sv per 5 yrs). The 30% criterion for monitoring then brings a lot of the
air crews into the monitoring program which further highlights their
exposures.
In the U.S. the criterion is 10% of 5 rem within the NRC and DoE community,
an even smaller monitoring threshold. But the fragmented regulatory
framework in the U.S. results in this not being applied by the FAA.
The NCRP annual meeting a few years ago discussed all this in great detail.
